Refrigeration equipment How big is the compressor used to build a 45 cubic meter cold storage?

High temperature cold storage (0-5) 4 hp hermetic compressor or 5 hp fully enclosed compressor is acceptable. If it is a medium-temperature cold storage (-15 --18), use a 7-horse fully enclosed compressor or a semi-enclosed 5-horse compressor. Low-temperature cold storage (-20 --35) requires 15 hp semi-hermetic compressor.

The compressor, a driven fluid machine that lifts low-pressure gas into high-pressure gas, is the heart of the refrigeration system. It sucks low temperature and low pressure refrigerant gas from the suction pipe, drives the piston to compress it through the motor operation, and discharges the high temperature and high pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle, so as to realize the refrigeration cycle of compression, condensation (heat release), expansion and evaporation (heat absorption).

5P compressors for freezers and compressors for refrigerators are fine.

A 5hp unit will do. Jinhua, Zhejiang.

What is the required temperature? High temperature, medium temperature and low temperature?

The 45 cubic meter cold storage is equipped with a cold fan and a 10-15 hp compressor.

First, the general calculation method of small cold storage is: 1 cubic according to 100-150w or so with compressor. ，.45 square meters is 7 kilowatts, and 10 horsepower is kilowatts. , using R22 refrigerant, choose a 10-15 hp cryogenic machine.

1. If the goods are meat or other items with a temperature above -5, although the 10 HP compressor can reach the required temperature, it has a long start-up time, and it is more suitable to have a larger power from the comprehensive consideration of large equipment wear. So it is recommended to use 15 horses.

2. If the incoming temperature of the goods is low and the incoming quantity is small, it is recommended to use 10 horses.

Second, the evaporator generally uses a cold air cooler, low cost and fast cooling, generally using DD type or DJ type air cooler, under this working condition generally 1KW needs 6 7 square evaporation area. So, the power of the air cooler is required at least.

Compressors of 5 kW or more are selected.

The cold storage of 10 square meters is a low-temperature storage, the height is calculated according to 3 meters, the total volume is 10 * 3 = 30 cubic meters, then the power of the compressor is 30 * 110 *.

No matter what brand of compressor unit, the selection is determined according to the evaporation temperature of the active cold storage and the effective working volume of the cold storage, and the condensation temperature, storage volume, and frequency of goods in and out of the warehouse should also be referred to the parameters of frozen or refrigerated goods.

Usually the formula for calculating the refrigeration capacity of high-temperature cold storage is: the volume of cold storage is 90 positive deviation, and the positive deviation is determined according to the condensation temperature of frozen or refrigerated items, the amount of warehousing, and the frequency of goods entering and leaving the warehouse, and the range is between 100-400w;

The formula for calculating the refrigeration capacity of medium temperature cold storage is: cold storage volume 95 positive deviation answer, positive deviation range between 200-600w;

The formula for calculating the refrigeration capacity of the low-temperature cold storage compressor unit is: the cold storage volume is 110 positive deviation, and the positive deviation range is 300-800w.

Summary. 1.Usually, the formula for calculating the refrigeration capacity of high-temperature active cold storage is: the volume of cold storage is 90 positive deviation, and the positive deviation amount is determined according to the condensing temperature of frozen or refrigerated items, the storage volume, and the frequency of goods entering and leaving the warehouse, and the range is between 100-400W;

2.The formula for calculating the refrigeration capacity of the medium-temperature active cold storage is: the volume of the cold storage is 95 positive deviation, and the positive deviation range is between 200-600w;

3.The formula for calculating the refrigeration capacity of the compressor unit of the low-temperature active cold storage is: the positive deviation of the cold storage volume is 110, and the positive deviation range is between 300-800W.

Hello, 120 cubic meters generally need to be more than 10p domestically.

You can customize this to the manufacturer according to your specific needs.

It is a pleasure to serve you, I hope mine can help you, I wish you a happy life.

With a 5p compressor.

The compressor is the primary equipment in the refrigeration system, through which it converts electrical energy into mechanical work, and compresses the low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gas to ensure the refrigeration cycle. In a vapor compression refrigeration system, the refrigerant is raised from low pressure to high pressure, so that the refrigerant is constantly circulating, so that the system continuously discharges internal heat into the environment.

The refrigeration compressor is the heart of the refrigeration system, through which the refrigeration system inputs electrical energy, thereby discharging heat from the low temperature environment to the high temperature environment. The energy efficiency ratio of the refrigeration compressor determines the power of the entire refrigeration system.

The details also depend on what goods are stored in your cold storage, as well as the way the goods are placed, the stacking density and so on.

No matter what brand of compressor unit, the selection is determined according to the evaporation temperature of the active cold storage and the effective working volume of the cold storage, and the condensing temperature, storage volume, and frequency of goods in and out of the warehouse should also be referred to.

Usually, the formula for calculating the refrigeration capacity of high-temperature cold storage is:

Cold storage volume 90 positive deviation, positive deviation according to the condensation temperature of frozen or refrigerated goods, storage volume, goods in and out of the warehouse frequency to determine, the range is between 100-400W;

The formula for calculating the cooling capacity of medium-temperature cold storage is:

Cold storage volume 95 positive deviation, positive deviation range between 200-600w;

The formula for calculating the cooling capacity of the low-temperature cold storage compressor unit is:

Cold storage volume 110 positive deviation, positive deviation range of 300-800w According to what you said, 10 square cold storage is low temperature storage, the height is calculated by 3 meters, and the total volume is 10 * 3 = 30 cubic meters.

Then the power of the compressor is.

30*110*, that is, the compressor above 5kw can be selected.

The question is too 'professional'
